CUTTER-HEAD.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed September 2, 1904. Serial No. 223.081.

T (LI/Z 1072,0771 it ntay concern:

Be it known that I, MONROE BUTTON, a citizen of the United States, and a resident of Fort Plain, in the county of Montgomery and State of New York, have invented a new and Improved Cutter-Head, of which the following is a full, clear, and exact description.

My invention relates to cutter-heads, and more particularly to those adapted for the making of window-sash. Its principal obj cots are to provide a strong and convenient head with which both the stiles and rails of sashes of various widths may be cut.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of one embodiment of my invention. Fig. 2 is a top plan view thereof, parts being broken away. Fig. 3 is a central longitudinal vertical section on the line 3 3 of Fig. 4. Fig. 4 is an end elevation looking from the left in Fig. 1. Figs. 5 and 6 are partial transverse sections through a stile and rail, respectively, such as are made with my improved cutter; and Fig. 7 is a perspective view of a gib for secur ing one of the cutters.

1O designates an arbor, which is provided with a fixed collar or enlargement 11 and with a threaded portion 12, situated at a suit able distance therefrom. This arbor is held in any convenient manner to rotate in the machine in which it is to operate. Mounted upon this arbor is a head-section S, it having a bore to receive said arbor and resting against the enlargement 11. As here illustrated, this section consists of a main or body portion 13, at each side of which are opposite recesses 14 14, which have their deepest portion at each side of the arboropening, there being an intermediate particylindrical enlargement 1 1*. From the head at the opposite side from its surface of a 16, between which is 1 lar space or recess. tion at the ends of the recesses extends a contact with the collar on the arbor is a tubular extension 15, projecting into proximity with the thread 12. At opposite sides of this extension are pairs of projections 16 a preferably rectangu- Through the body porchannel or opening to receive a molding outter or blade 18.

The working edge of this cutter has at the side toward the outer end of the section a straight portion 19, adapted 0 cut the outer bar a of both the style A and rail B, as shown in Figs. 5 and 6 of the drawings, a portion 20, which is of such contour as to produce the curved face I) of these sash members, and, finally, a considerably-extended straight edge 21, which will produce the center bar 0. Each cutter is preferably secured in its opening by a gib 22, having at each end an angular projection 23, extending at each side of the body portion. This gib is preferably forced into contact with the cutter to clamp it in place by screws 2 1, threaded through the projections 16. It will be seen that this gib receives the wear or indentation produced by the points of the screws, and thus avoids injury to the cutter, and that its end portions keep it always in the same relation to the head, preventing longitudinal displacement through the opening.

Cooperating with the first section is a second head-section S, here shown as consisting of a-hub 25, having a central bore of such diameter as to receive the extension of the companion head, Extending inwardly from a flange 26 of this hub are opposite arms or projections 27 27, lying adjacent to the recesses 14. The sections may be locked together by projections 28, radiating from the periphery of the flange between the arms and engaging the projections 16, the spaces be tween which they closely fit. Through the outer end of each arm is -a narrow inclined opening or channel in which is situated a cutter or plow 29, having its shank extending into the adjacent recess 14. This plow may be used to produce the glass and putty groove d of the rail B and is so situated with relation to the portion 21 of the cutter 18 that its adjacent side will always overlap or coincide with the side of said cutter. Each plow is preferably secured in place by a rod 30, lying within an opening extending longitudinally of one of the arms 27 and contacting at its innerend with the plow, while bearing against its outer end is a comparatively short screw 31, threaded into the outer end of the opening. While this screw transmits its pressure to the rod to bind the plow firmly in place, there is not the danger of twisting it off in securing the necessary force thatthere would be if it were extended the entire length of the opening. At the opposite side of each plow from the cutter 18 is an opening or channel extending through the arm from side to side and having opposite inclined side walls 31, with which contacts a cutter 32,

having similarly-inclined sides, but an extended straight edge lying parallel to the A when the planes of the inner edges coincide the cutter 32 will be operating to the proper depth to produce the rabbet e of the rail. Then upon being withdrawn, together with the plow, the side bar f of the stile may be out. These cutters 32 may each have an associated gib 33, similar to that previously described in connection with the cutter 18, but having its sides inclined. It is forced into contact with the cutter by screws 34, threaded into openings in the outer ends of the arm 27.

Fitting about the extension 15 are washers or spacing members 35, these being preferably substantially equal in diameter to the outer end of the hub and of various thicknesses. In assembling the tool for use these may lie either between the sections, as is clearly shown in Figs. 1 and 3 of the drawings, or between the end of the hub and a collar 36, which has an inwardly-extending annular flange 37 fitting over the extension 15 to contact with these washers. The sections, spacing members, and collars are forced together and against the enlargement 11 upon the arbor by a nut 38 operating upon'the threaded portion 12 of the arbor, preferably secured against slackening off by a lock-nut 39.

In stock sizes of sash the molded portion is commonly of the same thickness for all, while the thickness of the center-bar rabbet and side bar vary. In using my improved cutter-head the section S is placed upon the arbor with its cutters projected to such an extent as to make a cut of the proper depth. j WVashers of suitable thickness and in the proper number are then slipped over the extension 15 of this section, so that when the section S is applied they will bring its outters in the plane of the inner side of the rabbet of the stile and the glassgroove of the rail. The section S is now assembled upon the extension with the locking projections in engagement, when the remainder ofthe spacing members may be placed upon the end of the extension projecting beyond the hub and the flanged collar applied. Then upon screwing down the nuts the sections are clamped firmly against the arbor enlargement and together, they making, with the interposed washers, a continuous body over the arbor which will exclude dirt and chips, thus avoiding interference with future adjustments. In making the cut for the stile the edges of the cutters 29 and 32 may lie in the same cylindrical surface and operate together. Then when it is desired to form the rail it is only necessary to draw back'the cutter 32 to such an extent that it will form the side bar, leaving the plow to make the groove. This method of operating insures the surface against which the outer side of the glass rests being absolutely true. If another width of sash is to be made, the section S is removed and the spacing members shifted to produce the proper relation between the cutters, when the parts may be reassembled and the work performed as has been previously described.

It should be noted that whatever adjustment of the sections is employed the cutterhead remains of the same length between the end of the body portion of the section S and the outer face of the flanged collar, that a continuous closure is formed about the surface of' the arbor over which the head extends, and that the sections are maintained in absolutely true angular relation to one another, the locking projections sliding longitudinally, but preventing relative rotary movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cutter-head comprising a section having a body portion provided with opposite recesses, with a tubular portion and opposite locking projections, a second section having a hub encircling the tubular portion, arms extending near the recesses and locking projections engaging those of the other section, and cutters mounted upon the bodyportion of one section and in the arms of the other.

2. A cutter-head comprising a section having a body portion provided with opposite recesses, with a tubular portion and opposite pairs of locking projections, a second section having a hub encircling the tubular portion, arms extending near the recesses and locking projections extending between those of the other section, and cutters mounted upon the body portion of one section and in the arms of the other.

3. A cutter-head comprisinga section having a body portion provided with opposite recesses, with a tubular portion and opposite locking projections, a second section having a hub encircling the tubular portion, arms extending into the recesses and locking proj ections engaging those of the other section,

spacing members interposed between the sections and surrounding the tubular portion, and cutters mounted upon the body portion of one section and in the arms of the other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
